BClaims.

The present invention relates to liquid dispensing devices and hasparticular reference to the opening of sealed receptacles or canscontaining liquids such as lubricating oil and to the dispensing of theliquid contents, the opening action at the same time mutilating both endand side walls of the receptacle to prevent its re-use. In some respectsthe present invention is an improvement upon the Nicholls United StatesPatent No. 1,970,573, issued August 21, 1934, upon Liquid dispenser.

In the liquid dispenser of the Nicholls patent an 011 can is opened bypuncturing the top or end wall of the can. After the can was emptied itwas found that the entire top might be cut off from the body and thebody refianged, filled again with oil and a new top or end member seamedin place. This was, 01' course, a case of substitution for the markingon the outside of the can giving the original oil companys name, etc.,was no longer correct as in fact a poorer grade of oil was palmed oil onthe public who was deceived in thinking it was obtaining the originalhigh grade 011.

In some cases unscrupulous jobbers of oil succeeded in cutting away onlysuflicient of the double seam which joined the can cover with the canbody of emptied cans so that the punctured end could be lifted off ofthe can without mutilating the flange of the can body. Here again aninferior grade of oil was sealed into the can, it being merely necessaryto apply a new can cover.

An object of the present invention is the provision of a liquiddispenser which is adapted to' receive sealed liquid filled containerssuch as cans of lubricating oil and to hold them while opening andventing by a simple movement of the opening elements, after which theopened can still held in the holder, is emptied of its contents by asimple tipping action of the holder, the opening and venting operationof the dispenser simultaneously mutilating not only the end of the canbut also the side wall of the body so that such,

a can is rendered useless for refilling, it being impossible to reclosesuch a mutilated can without detection.

A further object of the invention is the provision of liquid dispensersof the character described having pouring spouts and a can openerelement operated at the time the can is opened to not only cut throughthe end wall of the can to permit dispensing of the liquid but also topass on and into the side wall so that the can body is mutilated, thisbeing done without any extra operation and without detracting in anymanner from the opening and dispensing action of the device.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, takenin connection with the accompanying drawings, discloses a preferredembodiment thereof.

Referring to the drawings:

A preferred embodiment of the invention such as is illustrated in thedrawings comprising a dispensing holder ll open at the top and closed bya bottom member l2. This holder is preferably provided with a handle I!formed with a horizontal straight upper section I disposed in ahorizontal line passing along the upper rim of the holder. The wall ofthe holder ll adjacent its upper rim is cut away at opposite sides as atl5 (Figs. 1, 2 and 3) and a sealed receptacle or can l6 containing aliquid such as lubricating oil may be placed into the holder, theopenings l5 permitting holding of the container by the fingers duringsuch positioning.

A pouring spout II is provided having a pair of side wings 22 at thebottom of the spout which are secured to the exterior front wall of theholder Ii. This pouring spout extends upwardly and at an angle andisslightly conical in form. The upper end of the spout terminates in atubular mouth or discharge opening and below this the spout is cut awayalong its top to provide a 65 clearance or transverse opening It for anopenin: lever 2.

The opening lever is preferably formed with sacedrearlessllconnectsdatthebackina Fig- It is when the opening lever IIis in its open The fairly snug fit within the holder as it sgtrestsliponthebottomlf,itslmperedgebeing substantiallyin linewiththetoprimof the holder. Inthisinsertedpositiontheopening and ventingof the can is effected by a shifting of the lever 24 as it is broughtdown into its closed or horizontal position over the can.

A hollow puncturing munber or cutter II (Figs. 2 and 6) is provided forcutting a dispensing opening in the can end and also for mutilating itsside wall. This cutter comprises spaced side walls 38 joined in front bya curved 40 blade I! which terminates in a depending piercing point It.In the rear the side walls 30 are Joined by a curved web I. The hollowcutter fl is located between the front spaced legs 20 of the openinglever and is held in fixed position between these legs by rivets or pinsii. The lower edges of the cutter side walls are sharpened or beveled asindicated at 42 (Figs. 3 and 5).

The lever It also carries a vent blade II which is locatedbetween therear legs 28 of the opening lever and which is held in place by pins I!seatedinthespacedlegwallsll. Thisvent blade is provided with a V-shapedpointed and beveled depending piercing edge I! which proiects below theopening lever, the blade being also out through with a transverseopening '4. Its use will be made apparent later.

The piercing edge of the vent blade II isenelosedmostofthetimeandforthismlrp e there is provided a protectingshield it formed with side walls I? which normally extend down below thepiercing point. These side walls at the front are pivotally mounted on apin it carried in the spaced legs of the opening lever.

when shielded the parts are in the position illustrated in Figs. 1, 2and 6, the shield frame being held down against the lever 24 by a springI. The spring is coiled around the pivot pin it and one end of thespring is inserted in an opening '2 (Figs. 5 and 6) formed in the upperwall of the shield member ll. The opposite end extends over and engagesa pin it held in the spaced legs II of the opening lever.

After the can I! is inserted within the holder II the opening lever isbrought down from its vertical position (fig.

just inside and adjacent its side wall.

l 'urther depre-ion of the lever forces the cutter ll into the can wallthe edge of the piercing member II and the two side cutting edges 42cutblade 81 in addition to cutting into the can end has passed entirelythrough the side wall of the can and has bent out a portion of the wall.During this cutting movement the web 89, engaging the severed section ofthe can end after it is out by the cutting edges l2, bends back thesevered can end section into the can. Fig. 4 illustrates the dispensingopening formed in the top of the can, this being designated by thenumeral I, a partofthewall asat i2 beingbentbackbythe web II. Theopening II, it will be observed, is bounded on the side by lines of cutdesignated by the numeral it, these being where the cutting edges 42 ofthe cutter entered the can end.

The curved blade 81 of the cutter is an arc of a circle having as itscenter the center of the pin I i this being the pivotal center on whichthe lever 24 moves. Accordingly when the lever is brought down into theposition illustrated in Fig. 5 the curved shape of the blade 31 causesits piercing point It to pass from the top end opening OI directly intothe side wall of the can adjacent its Junction with the top end. In.passing into and through this side wall a mutilated opening it (Figs. 4and 5) is produced. This opening destroys the usefulness of the can bodyand prevents re-use of such a body wall.

As the opening lever it approaches the end of its downward stroke butprior to coming into its final position of Fig. 5, the bottom roundededges of the side walls ll of the vent shield 58 strike against the topof the can and are stopped while the continued movement of the openinglever causes the shield to pivot on the pin I. The piercing point of thevent blade 5| engages and enters into the wall of the can during suchcontinued movement.

A vent opening I! (Fig. 4) is thus produced in the can top on theopposite side irom the dispensing opening II. The vent blade II remainsin this opening (Fig. 5) as long as the opening lever is in its closedposition and this is the position for dispensing. By reason of theopening '4 in the blade, air passes from the outside into the openingand thence enters into the can above the liquid.

The dispensing device with its confined and opened can may now be liftedby its handle II, the handle end of the opening lever 24 beingpreferably held down against the handle part II. Dispenser and can arethen tipped into the position illustrated in Fig. 5 for the discharge ofthe can contents.

The liquid flowing from the can passes out through the hollow cutter IIand through the dispensing opening ii in the can top and thence throughthe pouring spout 2| out through its discharge end where it is directedas desired. Some of the liquid may even pass through the mutilatedopening M in the side wall of the can although the curved bladesubstantially closes the opening. Any liquid passing through the openingdrops into the snout and eventuallv flows therefrom with the body ofliquid issuing through the dispensing opening During this discharging ofliquid frbm the can the air is entering through the opening 54 of thevent blade 5i as has already been explained. This air passes through thevent opening 65 in the can top wall and displaces the liquid as fast asit is drawn od. An easy dispensing action results.

Following a dispensing action and emptying of the can, the opening leveris returned to its non-operating position within the pouring spout. Theempty can may then be lifted out of the holder, easy grasping of the canby the fingers being possible by reason of the clearance openings IS inthe side walls of the dispenser holder as has already been explained.The ra ged can wall edge which is pushed out by the blade 31 at themaking oithe mutilated opening 68 passes into a clearance slot 61 (Figs.1 and 2) which is formed in the front wall of the holder H and thisclearance opening now permits lifting of the emptied can from its seatwithin the holder without interfering with the free sliding movement ofthe same.

By reason of the construction of the curved and fixed cutter member 35the desired kind of dispensing opening 6! is formed with a single strokeof the lever 24 and at the same time and without further movement of theblade 31 .other than its body movement by reason of the change ofposition of the lever'fl. In other words without'further effort and in asingle simple movement the operator opens the sealed can for easydispensing of its contents and mutilates it Feyond re-use. Dispensing ofits liquid contents is then a simple matter after which the can isremoved from the holder in the regular way.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form,

construction and arrangement of the parts without departing from thespirit and scope of the invention or sacrificing all of its materialadvantages, the form hereinbefore described-being I merely a preferredembodiment thereof.
